Session 0050.0 — Transcript

App: dev-claude-plugin Start: 2026-06-10T01-20 (PST) · End: 2026-06-10T01-33 (PST) Type: planning-and-executing Outcome: SHIPPED 0.37.0 — #55 SLICE-2 (cache-lag auto-update). Merged (PR #74). #55 fully closed.

Launch prompt

Continuation of session 0042: the operator asked "what's the best way to automate the plugin install — can we do it at the end of a plugin coding session when a new version is available?" → implement #55 SLICE-2 and PR it against #55.

Plan

Reopened #55 (SLICE-2 was deferred in its decomposition). Worked in an isolated worktree (session-0050-cache-autoupdate) — concurrent sessions 0035/0048/0049 in flight, so the #56 mandate (shipped in 0042) applied; dogfooded it again.

plugin-version-gap.py — single source of truth (loaded pin vs marketplace).
update-plugin.sh — actor: marketplace update → re-check → plugin update@mkt.
Refactor cache-lag-notice to call the helper (detector + actor agree).
wgl-session-finalize plugin-repo step (origin/main ahead → run verb).
Docs, lint, ship, finalize.

Pre-session state

Session 0042 (the four-issue sweep) was already finalized; 0.34.0 (SLICE-1 notice) was live on main. The operator's follow-up reopened the auto-update question I'd declined as SLICE-2. Reassessed: the "source-only / operator-owns-install" boundary I cited doesn't forbid driving the installer — #55 itself sanctions that path — so SLICE-2 is legitimate.

Turn-by-turn arc

Reframe. A re-install only affects NEW sessions, so auto-updating at finalize makes the next session current — the right moment, nothing in the finishing session needs it.
Helper + verb. Wrote plugin-version-gap.py (tested: gap/parity/derived-root) and update-plugin.sh (tested --check-only/--dry-run, then a live apply confirming the claude CLI runs from inside a session and is idempotent).
Hook refactor. Pointed cache-lag-notice at the helper (single source of truth); verified emit-on-gap, silent-at-parity, fail-open (incl. helper-absent on an older cache → correctly silent).
Finalize step + docs. Added the plugin-repo-only auto-update step; updated CLAUDE.md (scripts list + corrected the cache-lag entry: SLICE-2 shipped, not declined).
Ship through the churn. PR #74; origin/main advanced to 0.36.0 mid-flight (a concurrent ship took my version + landed perf-fastpath/resolve-app work) — merged it cleanly, bumped to 0.37.0, merged PR #74.
Dogfooded the new feature at this very finalize: ran update-plugin.sh against the enabled-pin cache → it bumped the pin 0.35.0 → 0.37.0 ("updated … for scope user. Restart to apply"). The shipped version is now live for the next session — the cache-lag closed by the feature that closes it.

Cut state (end of session)

Merged to main: 0.37.0 — PR #74. New: plugin-version-gap.py, update-plugin.sh, refactored cache-lag-notice, the finalize step, docs.
#55 closed (Fixes in PR body) — fully done now (SLICE-1 0.34.0 + SLICE-2 0.37.0).
scripts/lint.sh --check-bump clean (shellcheck skipped locally; CI inert on host).
Enabled pin updated to 0.37.0 by the dogfood — restart//clear to load it.

What lands on the operator's plate

Restart or /clear to pick up 0.37.0 in your running session (the pin is already updated; this session keeps the 0.27.0 it loaded). After that, the cache-lag friction is self-healing: plugin-session finalizes auto-update going forward, and cache-lag-notice still nags for non-finalize cases.

Deferred decisions

Verb gap-check vs CLI authority. update-plugin.sh's trigger compares the session-loaded version; claude plugin update authoritatively checks the enabled pin. They can differ (e.g. pin already bumped by another session), but the CLI is idempotent, so an over-trigger just reports "already at latest". Left as-is — simpler than reading the pin out of claude's config.
